Guilty, though I responded to the OPs "I'm amazed at the ignorance in these comments". You don't think that warrants the same comment?
I wish there were a way for users to suggest edits to each other's comments. My bet is that most of us have no idea when our comments include superfluous stuff that could easily be edited out. Suppose there were an easy way to send pull requests on comments. One could look at the diff and, if it improved the signal/noise ratio, simply accept the changes.
HN needs more sober second thought.
We're still interested in whatever might be done to curtail such downhill slides.
